Unidirectional Air Flow Benches offers highest product protection
for samples and processes by providing ISO Class 5 particle free work area. Unidirectional
Air Flow Unit draws air in through the top of the unit through a pre-filter, through
a plenum and vertically down over the work-surface and past the lap of the operator.
It has the advantage of not pushing air into the face of the operator as in a vertical
laminar flow cabinet.

It prevents contamination from operator and environment to work area. The laminarity
of the flow prevents cross contamination between the items handled in the working
space. These units are suitable for the handling of non-hazardous products, sensible
to dust and/or to contamination wherever operator protection is not required.

Unidirectional Air Flow Units with a variety of standard dimensions
also our cabinet can be custom engineered to any size. Unidirectional air flow are
available in powder coated Mild Steel, SS 304 / 316 / 316L or a
combination of both.
